SD-WAN

SD-WAN:

Increased deployment of cloud, SaaS, video and mobile applications has challenged IT and business managers to provide high-quality WAN services to the branch. Deploying and managing the WAN has become more challenging and costly as traffic flows decentralize.

Business and IT Managers are facing three major challenges:

Increased access cost for MPLS-based bandwidth to support application performance

High Complexity Branch Deployment

Architectural issues with traditional WAN that is both static and private, inhibiting the migration to dynamic and public cloud environments

Software-Defined WAN uses software and cloud-based technologies to simplify the delivery of WAN services to branch offices. Software based virtualization enables network abstraction that results in simplification of network operations.

Traditional Enterprise WANs use both an MPLS and single-function CPE for connectivity and security. This approach is expensive and deploying and managing proprietary hardware can be difficult with inflexible architecture and slow responses to service change requirements.

The transition to SD-WAN and software-defined security enables enterprises to significantly reduce total cost of ownership, increase their IT agility and take a DevOps (developers partner with operations staff to assure software implementation and performance success) approach to both security and the WAN.

Significantly Lower Total Cost of Ownership

Opex is also significantly reduced by eliminating or reducing branch office truck rolls, shortening help desk and troubleshooting time, and easily integrating new services into existing deployments. Scale the solution with the business, ensuring you only pay for what you use.

IT Agility

Roll out large-scale SD-WAN and branch security deployments quickly and without complex or proprietary hardware.

New deployments can be designed and validated in days. Network IT teams can adopt an agile, software-based DevOps model and remove the provisioning time and hardware dependency of traditional WAN and security architectures

Additional security functions can also be applied to the application traffic using direct Internet access, enabling stronger branch security, although MPLS traffic may not require it.

Simplify Support and Operations

Significantly reduce time spent on managing network and security services at the branch with zero-touch provisioning and centralized management – enterprises have experienced up to 50% in opex savings.
